Helically Symmetric Experiment
Overview
 
The Helically Symmetric eXperiment (HSX) is an experimental plasma
Plasma (physics)
In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized. Heating a gas may ionize its molecules or atoms , thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions...

 confinement device at the University of Wisconsin-Madison, whose design principles are hoped to be incorporated into a fusion reactor. The HSX is a modular coil stellarator
Stellarator
A stellarator is a device used to confine a hot plasma with magnetic fields in order to sustain a controlled nuclear fusion reaction. It is one of the earliest controlled fusion devices, first invented by Lyman Spitzer in 1950 and built the next year at what later became the Princeton Plasma...

Toroid
Toroid may refer to*Toroid , a doughnut-like solid whose surface is a torus.*Toroidal inductors and transformers which have wire windings on circular ring shaped magnetic cores.*Vortex ring, a toroidal flow in fluid mechanics....

al shaped pressure vessel
Pressure vessel
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.The pressure differential is dangerous and many fatal accidents have occurred in the history of their development and operation. Consequently, their design,...

 with external electromagnet
Electromagnet
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current is turned off...

s which generate a magnetic field
Magnetic field
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude ; as such it is a vector field.Technically, a magnetic field is a pseudo vector;...

Magnetic confinement fusion
Magnetic confinement fusion
Magnetic confinement fusion is an approach to generating fusion power that uses magnetic fields to confine the hot fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of fusion energy research, the other being inertial confinement fusion. The magnetic approach is...

 devices attempt to contain a hot plasma using a series of magnetic fields.
Quotations

"Communism is the end of the economy as a separate and privileged field on which everything else depends while despising and fearing it. It is used to refer to the economic power under Communist parties that have the dictatorship of the social classes." –Gilles Dauvé|Gilles Dauvé

"The true revolutionary is guided by great feelings of love. It is impossible to think of a genuine revolutionary lacking this quality.""There is no other definition of communism valid for us than that of the abolition of the exploitation of man by man."–Che Guevara|Che Guevara

"I worked at a factory owned by Germans, at coal pits owned by Frenchmen, and at a chemical plant owned by Belgians. There I discovered something about capitalists. They are all alike, whatever the nationality. All they wanted from me was the most work for the least money that kept me alive. So I became a communist."–Nikita Khrushchev|Nikita Khrushchev

"The political form of a society wherein the proletariat is victorious in overthrowing the bourgeoisie will be a democratic republic."–Vladimir Lenin|Vladimir Lenin

"Workers of the world unite!" –Karl Marx|Karl Marx

"Communism is for us not a state of affairs which is to be established, an ideal to which reality [will] have to adjust itself. We call communism the real movement which abolishes the present state of things. The conditions of this movement result from the premises now in existence." –Karl Marx|Karl Marx
